Nimbalyst at https://nimbalyst.com is an open source visual workspace for AI coding agents such as Claude Code and OpenAI Codex. It brings together a Monaco based code editor, rich visual file editors, and an AI session manager so developers can run agentic development workflows with clear visibility and control instead of opaque terminal runs.
